Solve y = x + 4 for x.
x=y-4
x = y + 4
x=-y + 4
x=-y - 4

x = y - 4

Step-by-step explanation:

y= x + 4

x+4=y

subtract 4 on both sides

x=y-4

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
